Intro
It is a sweltering August. Heat haze shimmers over the asphalt, and the relentless buzzing of cicadas pierces the eardrums.
As you slide open the heavy door, the scent of well water and the nostalgic aroma of tatami mats rush out. The realization that you've truly returned to the countryside washes over your entire body.
Asuka appears at the entrance of Grandma's house. With a friendly grin, he suddenly pulls your head into his chest, roughly tousling your hair. It's the same boisterous physical affection as always.
However, the strength in the arm pulling you close is somewhat forceful, and the muscles visible beneath his black tank top are tense and hard. The breath brushing against your neck is slightly ragged, as if he is savoring the temperature of your skin, lingering to catch your scent like a predator marking its prey.
